Hi guys,
it's been months since I posted but received my Sxynyx camera last week. Other than 2 large dust specs on the CCD chip (so it's going back for a replacement!) it looks like a really nice camera. A bit pricey but low noise and great tonal range. Should be awsome on Jupiter in a few months I think.
Attached are my first test shots taken of the moon - Messier & Messier A and Posidonious in poor conditions - 4/10 and wind.
Quick processing - just only alignment point 350 and 250 frames respectively and mild deconnvolution in Astra Image.
Only can capture at 20fps at the moment due to a slow laptop but this will change in the comming months.
Paul Haese (Rumples Riot) has offered some great advice on capture settings etc so should start getting some good images over the coming months. Filter wheel on the way.
great start with the new camera.......I had two signifcant dust specs on my new DBK luckily a magnifing scope thingy from a cleaning kit and a gitzo air blower got them off
I'm assuming the dust is on the sensor and under the filter glass? That would tick me off if it were so, as a quick flat frame test as part of QA would catch it.
Do you have to replace it because of dust? My DMK gets dust on it fairly regularly, and I just clean them off myself.
yep, looks like it's under the glass cover which covers the CCD, so unsure how you get to the CCD chip of this camera. Have tried using a blower to no effect.
It could be stubborn dust. I use a q-tip dipped in de-mineralised water, and gently wipe across the surface of the CCD. I used that technique with the ToUcam and the DMK and it gets rid of all the dust.
The de-mineralised water dries clear, and just leave it to dry with the chip almost vertical so most of it will run off.
I tried compressed air blowers etc, but it didn't always remove the dust.
The use of any water near any CCD is not recommended for cleaning. Not only will it void your warrantee, it could cause a short at some point in the future.
The recommended cleaning method is to use a sensor brush which is activated by using compressed air to statically charge the brush. Then wipe the brush gently over the surface of the CCD filter or CCD itself. Do this several times to completely clean the sensor. Sensor brushes can be bought from professional camera shops. Places like teds etc generally do not stock this equipment.
Like I said John call me for more information on use of the camera.
John, another possibility is to generate a "flat" image to compensate for this. I seem to remember seeing options in registax to load dark frames, maybe you can generate something to work with that?

Hi Anthony,
I think you are right, Registax and perhaps Photoshop can do that.
I guess I just did not expect to have stubborn dust/mark on the CCD for a new camera for this price/quality and straight out of the box with a CCD sensor that's factory sealed.
